摘要：PROBLEM TO BE SOLVED: To let have two functions of a pressure regulating valve and a pressure-raising/pressure-lowering valve for raising or lowering pressure, reduce the size and stably hold a t pressure of a fluid to suppress pulsation.SOLUTION: A pressure regulating drain valve 1 has a liquid chamber 3 formed with an inflow port 31 and a discharge port 32 for a liquid Q to be regulated in pressure, and a liquid pressure regulating mechanism 4 for regulating the pressure of the liquid Q. The liquid pressure regulating mechanism 4 compris a valve element 34 closing or opening the discharge port 32, an elastic member 5 imparting predetermined pressing force P to press the valve element 34 in a direction of closing the discharge port 32, a support member 6 supporting the rear end of the elastic member 5, a pressing force regulating mechanism F having a screw part 63 for advancing and retracting the support member 6 in the pressing direction of the elastic member 5 to regulate the pressing force P, and a pressure raising and lowering mechanism T for the liquid Q having a piston cylinder mechanism 9 for reciprocating the support member 6 in the pressing direction.SELECTED DRAWING: Figure 1
